Is there a way to prevent the ramdisk from swapping to disk? Perhaps by not storing so much stuff in it? That, or adding more RAM. Seriously, if you're going to fill up a large portion of your available memory with a ramdisk, demands for memory are going to have to be met by pushing pages out to swap space. By default, a ramdisk can grow to up to half of the available RAM after the kernel has been loaded. If programs and I/O buffers need more than the other memory you have available, what option is there besides swap? -- Bob Nichols "NOSPAM" is really part of my email address. Do NOT delete it.
